Architectural competitions have long offered a space for experimentation: platforms where ideas can be tested, typologies reimagined, and critical questions addressed through design. Freed from some of the constraints of commercial commissions, competition entries often reflect ambitious visions for how architecture can respond to environmental, cultural, and social challenges. Whether focused on future habitats, public institutions, or small-scale community infrastructure, these proposals give shape to the values and priorities driving architectural thinking today.
This month's Unbuilt selection brings together eight competition-winning projects submitted by the ArchDaily community. Each received first, second, or third place in recent local and international competitions. The featured proposals span a wide range of programs and geographies: a sustainable library in Lima, a Martian habitat exploring closed-loop systems, an adult orphanage designed for empowerment in India, a new French school in Athens, and a placemaking initiative in Singapore rooted in local folklore. While varied in scale and scope, they all highlight architecture's capacity to engage context, foster inclusion, and propose new ways of inhabiting space.
For centuries, the heart of the Arabian Peninsula was a land of vast deserts and settlements shaped by their environment. This relationship with the landscape, materiality, and knowledge of the place has not only endured but now translates into a landscape gaining recognition on the global creative scene. From projects that emerge with a profound sensitivity to context to global exhibitionsand awards that drive its evolution, the region is consolidating its architectural language—rooted in its history while oriented toward new explorations. Far from halting, this momentum continues to chart the path for its development, establishing the region as a platform in contemporary architectural discourse.

From 1977 to 1983, the National Theatre in Prague underwent a major transformation with the opening of Nová Scéna, a modern counterpart to the traditional Neo-Renaissance theatre. For many years, Nová Scéna hosted the renowned Laterna Magika, the world’s first multimedia theatre. This groundbreaking performance style combined classical theatre with computer-generated visual effects, creating a unique dramatic experience. The striking glass building, a symbol of the communist era, became an iconic representation of the political power of the time. In recognition of its significance, this building was part of the Open House Prague festival in 2024—an annual event that invites the public to explore and appreciate the value of architecture.
As a landmark of contemporary religious architecture in Portugal, the Church of the Sacred Heart of Jesus stands in contrast to traditional models, representing a work free from historicist stigmas. Resulting from a design competition organized in 1960, the church is notable for its civic dimension, urban role, and its anti-monumental and social significance. Integrated into the regular grid of the Avenidas Novas neighborhood, this example of the Movement for the Renewal of Sacred Art is part of a larger parish complex that often goes unnoticed by passersby. Its external street creates an unexpected public space, inviting people to enter and engage in a courtyard where architecture and the city merge. Finely crafted in terms of spatiality, detail, and light, the church holds many surprises for those who venture inside.
The landmark of Piraeus, located in the heart of the largest passenger port in Europe, began construction in 1972 but remained unfinished and vacant for decades. Finally completed in 2023, after an international competition, it now stands as Greece's first green and digital skyscraper. The architectural firm PILA took on the design of the facades, while the office ASPA-KST designed the commercial spaces, and the new general architectural study was entrusted to Betaplan. After over four years of renovation, Piraeus Tower officially opened its doors to tenants and visitors on June 4th with a night of celebrations, establishing itself as a bustling hub and injecting vitality into the area.

The team comprised of David Kohn Architects, noA Architecten, and Asli Çiçek has won the international competition for the redesign of SMAK, the Municipal Museum of Contemporary Art in Ghent, Belgium. The project includes the reconfiguration of the museum grounds and the extension of a cluster of historic buildings in the center of the city. Established in 1999, the Stedelijk Museum voor Actuele Kunst aims to redefine its relationship with the city and to create more appropriate space for the design of its extensive contemporary art collection.
In an open competition, ICON’s Initiative 99 requested participants to design a home using ICON’s 3D printing technologies while keeping the construction budget under $99,000. Among the three selected winners for the Open Category, New Zealand-based office MTspace Studio proposes a robust flood-resistant design, in response to the housing crisis in New Zealand’s flood zones. Titled “Wai Home” after the Māori word for water, the concept revolves around the idea of working with this essential natural element. The design features innovative rainwater collection and storage systems, along with elements to increase the resilience of the construction in the face of increasing threats.
Zaha Hadid Architects (ZHA) has been announced as the winner of the international competition for the design of the Riga Ropax Terminal in Latvia. Collaborating with Latvian practices Sarma Norde Architects and Alps Landscape Architects, as well as Sweco Finland, ZHA’s proposal includes the repurposing of an existing shipping warehouse, to be transformed into a key multi-modal transport hub for the city, located along the Daugava River. The competition was open to anyone who qualified. Out of the ten registered entries, the third prize was awarded to US-based Berenblum Busch Architects, the second prize went to R-Konsult from Estonia.
Housing is a diverse architectural typology whose configuration is determined not only by those who design it but also by the use of those who live in it. Therefore, homes are fundamentally adaptable structures that evolve in line with their time and users, undergoing constant changes manifested in the ways of living. The house conceived today will not be the same as the one built tomorrow, so it becomes necessary to maintain a critical and profound approach to the role it plays in the built environment.
In this sense, modular architecture has consistently presented itself as a dynamic design strategy that has revolutionized housing, developing versatile solutions for sustainable spaces and construction practices. Thus, modular housing has been fertile ground for exploring and deepening ways of inhabiting space and addressing human needs. From the prefabricated catalog houses of the 19th century to the post-World War II housing boom, its evolution reflects both past proposals and the exploration of new concepts for the future.

Winter Stations, now in its 10th year, has unveiled the winning designs selected from a pool of hundreds of submissions worldwide. Following an international design competition launched in November 2023, designers, artists, and architects contributed with bold proposals to reimagine the lifeguard stations along Toronto’s east-end beaches for the winter. Launched by RAW Design, Ferris + Associates, and Curio in 2014, the event aims to gather an international design and art community to join in this playful exercise of rethinking public spaces through bold temporary interventions. The winning designs were realized with the support of Anex Works, a Toronto-based fabrication group, and will be on display until the end of March.
For its 10th anniversary edition, the chosen theme for this year is “Resonance,” hoping to challenge designers to reflect on the artistic legacy and enduring impact of the Winter Stations and to embark on a journey of reinvention and reimagination. The projects were invited to recreate and reinvent installations from previous Winer Stations editions, offering moments of contemplation and remembrance. The event also continues the tradition of the Lifeguard Sands, inviting designers to incorporate them into their designs without structurally altering the stands in any manner.
